🔍 Key Concepts

• Towing gear materials and how they behave under abrasion and shock loads • Differences between chain and wire rope when they rub on chocks, bitts, or fairleads • Practical considerations in towing: handling, wear, and load distribution

💭 Think About

• Think about which material will hold up better if it is constantly rubbing against metal surfaces during a tow • Consider real-life towing: which would you expect to get cut, flattened, or worn more quickly when dragging over a sharp edge? • Ask yourself which of these options describes a physical property that is clearly different between chain and wire rope

✅ Before You Answer

• Compare resistance to chafing/abrasion for chain versus wire rope • Consider whether “handles more easily” realistically applies to heavy chain compared to wire rope • Decide if “better suited for inland towing” or “equalizes towing forces better” are specific, known advantages of chain, or just vague sounding statements
